This costume is the one I most seriously considered this year before I decided on one that better suited my budget, energy level, and actual Halloween plans. Behold, the last of my cosplay delusions:

If you are unfamiliar with Princess Bonnibel Bubblegum, the scientist who rules the Candy Kingdom in the Land of Ooo, click the picture below to see PB’s page on the Adventure Time wiki.
